| Abstract Scope |
Metal Cu nanomaterials have been increasing studied because of unusual properties and potential applications in electrode modification, electrical conductivity and microdevices. In this work, Cu dendritic nanostructures are synthesized through an electroless deposition route between Zn foil and Cu+ or Cu2+ in aqueous solution. The difference of reduction potential between Cu2+/Cu pair and Cu+/Cu pair modifies the deposition of copper leading to the unlike of morphologies, structures and properties of obtained Cu dendritic nanostructures. Nanoparticle-aggregated copper mesocrystal is observed for the production obtained from the reaction with Cu+. In contrast, there is only single crystal in the reaction with Cu2+. Diffusion-limited and oriented attachment mechanisms are adopted to account for the formation mechanism of Cu dendritic nanostructures. Most importantly, these results reported in this work provide insights into the mechanism for dendritic nanostructures formation via electroless deposition as well as a general way to fabricate other nanomaterials. |
